Diagrammatic summation is a common bottleneck in modern applications of projected entangled-pair states, especially in computing low-energy excitations of a two-dimensional quantum many-body system. To solve this problem, here we extend the generatin

Abstract We investigate interacting disordered zigzag nanoribbons at low doping, using the Hubbard model to treat electron interactions within the density matrix renormalization group and Hartree-Fock method. Extra electrons that are inserted into an

Quantum magnets are a promising platform to aid in the search for a Bose-Einstein condensate and investigations into the underlying mechanisms of these materials are an active area of research. Here, the authors present a numerical study of the two-d

We use Monte Carlo simulations and tensor network methods to study a classical monomer-dimer model on the square lattice with a hole (monomer) fugacity z, an aligning dimer-dimer interaction u that favors columnar order, and an attractive dimer-dimer

Despite the tremendous advances in the past few decades, the clinical problems associated with low mechanical strength, thrombosis, and inadequate endothelialization still have not been improved in small diameter vascular grafts. The objective of thi

$$\alpha$$ α -RuCl$${}_{3}$$ 3 is a candidate Kitaev spin liquid but whether or not this is realised depends on the details of the magnetic interactions. Here, the authors use state-of-the-art numerical methods to predict that for a large parameter

Depression is accompanied by neuronal atrophy and decreased neuroplasticity. Leucine-rich glioma-inactivated protein 1 (LGI1), a metastasis suppressor, plays an important role in the development of CNS synapses. We found that LGI1 expression was redu

Topological transport of fermions is governed by the Chern numbers of the energy bands lying below the Fermi energy. For bosons, e.g., phonons and magnons in a crystal, topological transport is dominated by the Chern number of the lowest energy band

We propose a simple and generic construction of the variational tensor network operators to study the quantum spin systems by the synergy of ideas from the imaginary-time evolution and the variational optimization of trial wave functions. By applying
